The critically acclaimed "Cat Who" series consists of 29 mystery novels and three story collections by former lifestyle writer and editor Lilian Jackson Braun. The series revolves around newspaper reporter Jim Qwilleran and his two Siamese cats, Koko and Yum-Yum, who help him to solve crimes.
Braun published the first three novels between 1966 and 1968 and did not release another until Berkley Publishing's 1986 offering of "The Cat Who Saw Red." Berkley quickly followed with four new novels and reprints of the original trio over the next two years. Then G.P. Putnam’s Sons picked up publication rights, offering 17 new books and concluding with "The Cat Who Sang for the Birds" in 1998.
Braun passed away in 2011, at the age of 97 but not before seeing her novels translated into 16 languages and appearing regularly on the bestseller lists. A 30th novel, announced in 2008, had to be canceled due to her death. Since her partnership with Putnam, she had released at least one new novel per year up until 2007. She said that America's substantial number of cat-lovers gave her books a large fan base. Satirist Robert Kaplow, parodied the series in 2003, with his novel “The Cat Who Killed Lilian Jackson Braun.”
